With the Repertory of St. Louis Celebrating its 50th anniversary this year, nostalgia is sure to abound. It’s especially fitting now for the Rep to open its new season with Stephen Sondheim’s Follies, a musical that explores both good and bad aspects of nostalgia, and reflects on hopes, dreams, regrets, and the power of memory. It’s also a pastiche of old Broadway themes and styles, and on stage at the Rep, it looks and sounds positively stunning.

The stage at the Rep is constantly changing in this production, thanks to Luke Cantarella’s vividly realized set design that makes excellent use of a turntable. The space represents an old, dilapidated Broadway theatre that is due to be demolished, and it’s haunted by the “ghosts” or memories of the elaborately dressed showgirls who used to perform there. The theatre becomes the scene for a reunion of many performers, mostly women, who participated in the “Weismann Follies” between the World Wars. They have been invited there by Follies producer Dimitri Weismann (Joneal Joplin) so that they can reconnect, remember, reflect, and say goodbye to the old theatre that was such an important part of their lives in the past. Among the various Follies alumni are former roommates Sally Durant Plummer (Christiane Noll) and Phyllis Rogers Stone (Emily Skinner), who are now middle-aged and married to the former “stage door Johnnies” who used to court them at the theatre. Sally’s husband Buddy (Adam Heller) is a salesman who loves Sally but has been worn out by years of feeling rejected by her. Sally still carries a torch for Ben Stone (Bradley Dean), who was involved briefly with Sally when they were younger but chose to marry Phyllis instead. Phyllis, stuck for years in an unhappy marriage to the well-connected, well-known politician Ben, is forced to confront her own choice to marry and stay with him, as well as trying to reconcile the idealistic but unrefined young woman she used to be with her more sophisticated but jaded present-day existence. All four have younger counterparts (Sarah Quinn Taylor as Young Sally, Kathryn Boswell as Young Phyllis, Michael Williams as Young Ben, and Cody Williams as Young Buddy) who interact with their present-day selves in a series of flashbacks, vestiges of memories. Meanwhile, the other Follies performers relive their glory days by performing their signature numbers and reflecting on their own lives in show business and elsewhere. And then there’s the stylized “Loveland” sequence in the second half of Act 2. This is a complex, multi-faceted show that provides an excellent showcase for most of the members of its large cast.

That superb cast is led by the extraordinary performances of this production’s Sally and Phyllis, Noll and Skinner. Noll brings a childlike quality to Sally that is ideal for the role of the middle-aged regretful starlet-turned-housewife who continues to delude herself by living in the past. Her rendition of Sondheim’s classic “Losing My Mind” is achingly real. Skinner, as the seemingly tougher, caustic Phyllis, allows the audience to see the vulnerability that lies beneath her outward steeliness. She delivers a devastating interpretation of “Would I Leave You?” and an energetic, clear performance of her song that outlines her inner conflict between who she was, who she is now, and how she wishes she could be in “The Story of Lucy and Jessie”. Heller brings a great deal of sympathy to the disillusioned, weary Buddy, who pines for a real relationship with Sally and lives in the shadow of her memories of Ben. For his own part, Dean plays Ben with just the right mixture of charm, regret, and confusion, bringing a lot of raw emotion to his big number in the “Loveland” sequence, “Live, Laugh, Love”. Taylor, Boswel, Michael Williams and Cody Williams are also excellent as the leads’ younger selves, and the rest of the cast is simply stellar. There are top-notch turns from Nancy Opel as former Follies girl turned TV star Carlotta, whose ode to a life in showbiz, “I’m Still Here” is a highlight. There’s also the terrific Zoe Vonder Haar singing the classic “Broadway Baby” with strength and style, an excellent haunting version of “One More Kiss” by Carol Skarimbas as the oldest of the alums, the gloriously voiced Heidi Schiller, in duet with the also great Julie Hanson and her younger self. And perhaps best of all is E. Fay Butler as Stella Deems leading the rest of her follow Follies alums in a spectacularly choreographed tap number, “Who’s That Woman?” that stops the show.

Visually, this show is simply a treat as well, with that spectacular, constantly morphing set and Amy Clark’s marvelous, colorful costumes that help bring the Follies atmosphere to life. The atmosphere of the early 1970s and the various preceding eras is ideally realized. There’s also wonderful lighting work by John Lasiter that helps set the mood particularly in the flashback and fantasy sequences, and top-notch sound design by Randy Hanson.

I had been looking forward to this production, being a Sondheim fan and having seen the excellent 2011 revival on Broadway. At the Rep, the show is just as spectacular as anything on Broadway. It’s a poignant reflection on how the past informs the present, as well as a glorious celebration of classic musical styles from the first half of the 20th Century. It’s at turns thrilling, funny, dramatic and heartbreaking. Follies is a spectacular way for the Rep to start off its historic 50th season. Go see it while you can. It’s not to be missed.
